Four battery banks support 12-volt DC power: 1) Main engine battery (1 8D); 2) Generator start battery
(1 4D); 3 ) house battery bank (2 8D); and 4) Bow thruster (1 8D).
Your 12 volt panel shows all the systems supported by your batteries. Primarily you will be turning on
the breakers for your lights, water pressure, electronics, etc. The one exception is the DC switch for the
Fresh Water Wash Down. This switch is located at the lower right of the AC panel. Bilge pumps
should always be left on (Auto) and are on a separate panel under the main 12 volt panel.
House Battery Bank & Switch
The HOUSE BATTERY BANK provides power for all DC systems, except the engines and automatic
bilge pumps. When disconnected from shore power, all 12-volt devices drain the house battery. Use
devices as needed.
The Xantrex PathMaker is a battery combiner that automatically connects 2 or three battery banks for
simultaneously charging and isolates them during discharge.
When a battery bank is being charged, the voltage will read from about 13.1 volts to 14.4 volts
depending upon state-of-charge of the battery bank. When the battery bank is at rest, (that is, not being
charged), the voltmeter can give a rough indication of the state-of-charge of the battery bank.
All batteries are charged by the engine ALTERNATOR while underway. The engine/house batteries are
charged by the BATTERY CHARGER when connected to shore power. Ensure the Battery Charger and
Inverter circuit breakers at the electrical panel are ON. The GENERATOR will also charge the batteries
as long as the Battery charger and inverter breakers are on.
Battery turn off switches are locate below and to the right of the lower wheel behind a teak and glass
door.
SANITATION SYSTEM

Marine Toilet

The sanitation HOLDING TANK holds 60 gallons. There is a Tank Watch warning panel located below
the engine controls at the lower helm on the right but do not rely solely on it. Sixty to eighty flushes
means you're getting close to needing a pump-out.
The vessel is equipped with two fresh water electric marine Tecma toilets. Each toilet has an adjacent
control panel with two buttons. The button on the left is labeled "BEFORE USE"; the button on the
right is labeled "AFTER USE". To conserve water, the following procedures are highly recommended.
For urination, simply use the toilet and then press the "AFTER USE" button. For solid human waste,
first press the "BEFORE USE" button to pre-fill the bowl. When you are done, press the "AFTER USE"
button. A few seconds after the flush a macerator pump will move the effluent to the holding tank.
